There are several cases of itchy acne on the body: 1. Infectious soft wart, a disease caused by human infectious soft wart virus infection, can appear round pockmarks on the skin rash, with a sense of navel depression on the top, smooth surface, and some itching. In treatment, recombinant human interferon α 2B ointment, imiquimod ointment, mixed retinoic acid ointment or tazarodine gel can be applied for treatment. You can also choose sterile tweezers to scrape the wart body to make it necrotic and fall off, so as to achieve the therapeutic effect. 2. Folliculitis, caused by bacterial infection such as Propionibacterium acnes, can appear conical papules, with pustules on the top, and can be externally applied with compound polymyxin B ointment or fusidic acid ointment.
